Loosn-LEAr-Bmnnn snnn'rs AND nnvrcn m mamrutarme THE sunApplicationfiled october 8, 1927. Serial No. 224,872.

This-application constitutes a continuation in part of my pendingapplication filed November 30, 1926, Serial No. 151,621, for an improvedvisible loose-leaf index and record,

and the present invention relates to sheets for a loose-leaf binder anda device for manipulating the same and more particularly to a device tobe used in connection with looseleaf visible indexsheets of thecharacter employed in loose-leaf binders shown in sa d application. j

Among the objects of the present invention are, to provide a device ofthe character specified that may be advantageously employed forinserting, spacing, and removing collectively, a series ofloose-leafindex sheets; and, to provide a device for manipulating the sheetswithout necessity of removing the cover'of the binder or opening theprongs or rings or separating the posts employed in the binder forconnecting these sheets.

Other objects and advantages of the present invention will be pointedout herein or be apparent from the description taken in connection withthe accompanying drawings.

In the drawin s:

Fig. 1 is a plan view of the device embodying my invention;

Fig. 2, a side elevational view, showing the top or cover member of thedevice raised a slight distance above the lower or base member;

Fig. 3, aplan view, showing a series of loose-leaf visible index sheets,with the device embodying my invention shown in connection therewith.

Fig. 4. is aplan view of the device shewing the top member in a modifiedform- As illustrated and as preferred, the device or means formanipulating the sheets of a loose-leaf binder comprises a base member 5consisting of a stripof sheet material formed or provided with a seriesof upstanding alinednniformly spaced pins 6; and a similar top or covermember 7 having a series of correspondingly spaced perforations 8 in theform ofslots opening at one-edge thereof.

' These two members 5 and 7 are joined toso gether at one end by a rivetor other suitable means designated by the numeral 9. It will be notedthat the connecting member 9 is of such a character as to permit a looseconnec- 'tion between said members 5 and 7. This as loose connection isfor the purpose of permitting both a horizontal adjustment or movementof the top member relatively to the bottom member 5, as shown by. Fig.1, and also a vertical movement of said member 7 relative to the member5, as shown by Fig. 2.

' I prefer to form the member 5 from a thin flexible metallic materialsuch, for example, as aluminum. The member 5 may be made of the samematerial or a different material.

The device is designed to be used in connectionwith a series ofloose-leaf visible index sheets, and in Fig. 3 of the drawings, I haveshown a series of these sheets indicated generally by the numeral YO. Asshown, each sheet 10 is provided with a slotted portion 11 for thepurpose of securing the sheets to.the

posts, prongs, etc. of a loose-lea-fbinder, not w shown. In addition tothe slots 11, the sheets i are formed with a series of openings orperforations 12 spaced at distance apart corresponding to the distancebetween the pins of the member 5.

From the above, it will be. noted that the 1 device may be readilyapplied to a series of sheets 10 by inserting the pins 6 of the lowermember 5 into the openings 12 of thesheet-s. After this is effected,upper member 7 is swung towards member 5, so that the slots thereof willreceive the ins 6 of member 5, and the sheets will thus I e securelyclamped between the members of the sheet-manipulatmg devlce and may becollectively inserted,

spaced, and removed from the binder in a quick and convenient manner. I

It will be further noted that a series of loose-leaf visible indexsheets may be inserted, removed, or shifted from one position to anotherposition within the binder in one operation, while retaining theindexing relationship to each other and without the necessity ofseparating rings or prongs, or remov ing the top cover of the bindnforthe purpose of changing',,the positiori'of the sheets therein. q

The use of the sheets of the character above described requiresafrequent shifting of a 7 group relatively to the posts or rings of thebinder, in order to insert one or more new sheets in their proper order,or to readjust the sheets when one or more are removed, and by the useof the device as herein shown and described, the manipulations may bereadily eflzected- Referring to Flg. 4, I have shewn a modification ofFig. 1. In this illustration the top member 7 does not have any notchesto receive the pins but instead isfiiade of narrower width and ispivoted at one side of the center of the base member and of the line ofpins so as to lie normally against one side of the pins or to be swungfreely away from them and to one side of the base.

I claim:

1. A device for manipulating the sheets of a loose leaf bindercomprising a base member and a top member means for pivotally connectingsaid members at one end of the device to permit vertical and horizontalswingingmovements of the top memberrelative to the base member.

2. A device for manipulating the sheets of a loose leaf bindercomprising a base member and a top'member, means for pivotallyconnecting said members at one end of the device to permit vertical andhorizontal swinging movements of the top member relative to the basemember, said base member provided with aseries of spaced-apart verticalpins.

3. A device for manipulating the sheets of a loose leaf bindercomprising a base memher having a series of projecting pins, a topmember formed with openings at one edge from one side thereof a distancecorresponding to the parallel distance apart a series of openings arearranged from the post-attaching openings on said sheets, a top memberand means for pivotally connecting said members at one end of the deviceto permit vertical and horizontal swinging movements of the top memberrelative to the base.

5. A loose leaf having a series of slotted post-attaching portions, saidportions in-' cluding a circular opening and a slit extending from thebinding edge to said opening and a second series of openings parallelwith the series of openings of said slotted portions and adapted toreceive the corresponding spaced pins on a sheet-manipulating device.

In testimony whereof I afiix my signature.

HENRY SCHOOLBERG.
